linux下資料庫執行個體開機自啟動設定

linux下資料庫執行個體開機自啟動設定1、修改/oratab

[root@org54 ~]# vi/etc/oratab     --把N改為Y，如下提示

# This file is used by ORACLEutilities.  It is created by root.sh

# and updated by the Database ConfigurationAssistant when creating

# a database.

 

# A colon, ':', is used as the fieldterminator.  A new line terminates

# the entry.  Lines beginning with a pound sign, '#', arecomments.

#

# Entries are of the form:

#  $ORACLE_SID:$ORACLE_HOME:<N|Y>:

#

# The first and second fields are thesystem identifier and home

# directory of the databaserespectively.  The third filed indicates

# to the dbstart utility that the databaseshould , "Y", or should not,

# "N", be brought up at systemboot time.

#

# Multiple entries with the same$ORACLE_SID are not allowed.

#

#

#game:/u01/app/oracle/product/10.2.0/db_1:N   --dbca建立庫時註冊的預設資訊

--格式：$ORACLE_SID:$ORACLE_HOME:<N|Y>   

--<N|Y>選項代表開機是否自啟動

game:/u01/app/oracle/product/10.2.0/db_1:Y

2、編輯/dbstart

[oracle@org54 bin]$ cd$ORACLE_HOME/bin

[oracle@org54 bin]$ ls-ll |grep dbstart

-rwxr-xr-x 1 oracle oinstall    10415 Jan 1  2000 dbstart

[oracle@org54 bin]$ vidbstart

--dbstart為開機自啟動指令碼，讓系統開機就去執行dbstart指令檔，它會去讀oratab檔案，讀到Y就會把對應的執行個體開機自啟動

--調整或確認監聽路徑，如ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle或ORACLE_HOME_LISTNER=$ORACLE_HOME根據設定的監聽調整路徑

 

 

3、編輯/rc.local

[root@org54 ~]# vi/etc/rc.d/rc.local  --添加如下兩行資訊，啟動執行個體、啟動監聽

#!/bin/sh

#

# This script will be executed *after* allthe other init scripts.

# You can put your own initialization stuffin here if you don't

# want to do the full Sys V style initstuff.

touch /var/lock/subsys/local

modprobe hangcheck-timer hangcheck_tick=30hangcheck_margin=180

su - oracle -c"/u01/app/oracle/product/10.2.0/db_1/bin/dbstart"

su - oracle -c"/u01/app/oracle/product/10.2.0/db_1/bin/lsnrctl start"

--命令中-c代表執行指令碼，指令碼dbstart中指定啟動的執行個體，指令碼lsnrctl中啟動配置的監聽

 

4、重啟驗證

# reboot

[oracle@org54 ~]$ sqlplus'/as sysdba'

小結：

linux下設定執行個體自啟動有關指令碼：

oratab：執行個體是否自啟動的註冊資訊

dbstart：開機啟動指令檔會讀取oratab資訊

rc.local：開機後立即要做的檔案
